【摘要】 近年来随着LED产业的发展,LED光源在背光应用领域也在不断拓展。本文主要从LED直下式背光源的结构特点探讨,如何提高亮度和均匀性,用光学软件模拟了用大功率白光LED实现高亮度和均匀性的背光模组,用实验数据验证了最初理论结果。并对LED直下式结构模组和LED侧入式结构模组的优缺点进行了对比和全面分析,及直下式LED背光结构在背光源系统的各个领域广泛应用的必然性。更多还原

【Abstract】 In recent years, with the development of industry, LED backlighting applications in LED light source in expanding. This article mainly from the back light LED structure characteristics, discusses how to improve the brightness and uniformity, use the software to simulate the optical power with high brightness and white LED the uniformity of backlight model, with experimental data shows that the original theory. And straight down to LED structure module and LED the lateral structure module and compares the advantages and disadvantages of the comprehensive analysis, and direct the type LED backlighting system structure in the back light all fields of the inevitability of wide application.更多还原
